Embodiment 1

[0148] Example 1 Preparation of Manganese Thiazole 2.5 Hydrate (Type V Compound)

[0149] At room temperature, add 7.99g of 2-amino-5-mercapto-1,3,4-thiadiazole to a 250ml flask, add 30ml of water, stir, add a solution of 2.45g of sodium hydroxide dissolved in an appropriate amount of water, stir, and then Add a solution of 5.071 g of manganese sulfate monohydrate dissolved in a proper amount of water, stir at about 40°C for about half an hour, take it out to cool, filter with suction, wash the solid with a small amount of water until there is no sulfate ion, and filter with suction. The obtained solid is diluted at about 52°C Blast drying for about 4 hours to obtain 8.2 g of brown-gray solid; melting point: greater than 280°C; water content determined by the Karfel method is 12.47%, thermal analysis: platform weight loss is about 12.68% (see attached figure 1 ), there is a corresponding endothermic peak (DTA) under the weightless platform (see attached figure 1 ), which is with...

Abstract

The invention discloses an efficient pollution-free growth-promoting agricultural new compound thiazole manganese v-type compound. According to the invention, the compound is low in energy consumptionin the preparation process, easy to prepare, environmentally friendly, low in hygroscopicity and good in storage stability or prevention and treatment effect and the like, and is suitable for preparing a composition containing the compound, pesticides for preventing and treating various bacterial and fungal diseases on crops and / or promoting the health or growth and development of crops, or medicaments for protecting industrial materials from being invaded by germs and other fields.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to provide a new compound with better stability of broad-spectrum bactericidal manganese thiazole, an agricultural composition thereof, and a preparation method and application thereof. Background technique [0002] Manganese thiazole, the chemical name is bis(2-amino-5-mercapto-1,3,4-thiadiazole) manganese, molecular formula C 4 H 4 N 6 S 4 Mn, molecular weight 319.31, manganese thiazole is a synthetic organic manganese broad-spectrum fungicide, which has multiple functions such as systemic, conduction, prevention, protection, and treatment, and its therapeutic effect is greater than its protective effect. It is used to prevent and control crop bacterial diseases A new generation of high-efficiency, low-toxicity, and broad-spectrum fungicide has good control effects on bacterial and fungal diseases. It can be widely used in the control of various bacterial and fungal diseases of crops...
